Abstract

A method of producing a polyurethane molded article is provided, in which one molding machine which can provide distinctly polyisocyanate component(s) and two kinds of polyol components is used, and prior to completion of the feed of a first polyurethane mixture liquid containing a polyisocyanate and a polyol component without a blowing agent into a mold, a second polyurethane mixture liquid containing a polyisocyanate and a second polyol component with a blowing agent is fed into the mold. The method produces, in a single stage, a polyurethane foam molded article having the skin or high density portion selectively formed on portions of the molded article actually requiring them, where the proportions of the skin and the high density portion and the foamed core can be varied freely.
